Studies like this show that this is a false choice, there is no real option to 'choose the economy' for example. As we saw from studies of the Spanish Flu, cities with late and light lockdowns actually suffered more economically than cities that locked down earlier and tighter because the effects of an un checked (or less well managed) outbreak that lasted longer were so devastating. More people sick and dying is a huge drag on activity, including all the people that have to look after them, and people self-isolate anyway out of fear. Pandemics like this are a juggernaut, there's no real option to ignore and carry on.
